I-NASA incike ku-RISC-V ukuze ibe inkomba ye-ecosystem yemishini yasemkhathini yesikhathi esizayo

SiFive, umsunguli kanye nomholi wekhompyutha I-RISC-V, imenyezelwe kuwebhusayithi yayo oficial ekhethwe yi-NASA hlinzeka umnyombo we iprosesa yekhompyutha yendiza yemkhathi ukusebenza okuphezulu (HPSC) isizukulwane esilandelayo.

Iphrojekthi ye-NASA ye-HPSC ithuthukisa ubuchwepheshe bekhompiyutha yendiza izohlinzeka okungenani izikhathi eziyikhulu umthamo wekhompyutha yamakhompyutha endiza yamanje. I-NASA yayimemezele ngoJuni ukuthi iphrojekthi yayo ye-HPSC izohlinzeka ngama-chips asanda kuklanywa ama-multicore, anama-cores amaningi okucubungula ku-chip ngayinye, kanye nesofthiwe yokusebenza yokuwaqhuba.

Ithimba lonjiniyela be-NASA liphethe indlela yokuthuthukisa i-HPSC futhi lihlinzeka ngokuphathwa kobuchwepheshe bomklamo nokulethwa kwama-chip chips. LImisebe yemvelo esemkhathini ilimaza izingxenye zikagesis, ekugcineni ibenze bahluleke, futhi yethula amaphutha ezibalo ezenziwa lapho. Futhi, ngenxa yesikhathi esisithathayo ukuze amasignali ahambe esuka eMhlabeni aye ezindaweni ezikude emkhathini, imisebenzi eminingi yasemkhathini kumelwe yenziwe ngaphandle kosizo lwemishini esemhlabeni.

I-HPSC izoklanywa ngokuqondile ukuthi ingene esikhaleni futhi izoqukatha izici eziyivumela ukuthi isebenze futhi inikeze imiphumela enokwethenjelwa engasetshenziselwa imisebenzi ebaluleke kakhulu edingekayo: isibonelo, ukuhlala ngerobhothi noma ukundiza kwenye iplanethi, ukusiza osomkhathi basuke eMhlabeni, noma ukusebenza eduze nemizimba emincane uhlelo sonozungezilanga olungaphandle.

Ngoba amandla kagesi avamise ukushoda. i-HPSC yakhelwe ukuthi ikwazi ukucubungula idatha ngokushesha izikhathi eziyi-100 kunamakhompuyutha amanje afanelekela isikhala ukusebenzisa amandla afanayo. Iphinde ivumele imisebenzi ukuthi ivalwe uma ingasetshenziswa futhi amandla ehliswe lapho kungadingeki.

I-HPSC kulindeleke ukuthi isetshenziswe cishe kuyo yonke imisebenzi yasemkhathini ezayo., kusukela ekuhloleni iplanethi kuya emisebenzini yenyanga ne-Martian. HPSC uizosebenzisa i-280-core SiFive Intelligence X8 RISC-V vector core, kanye nezinye izici ezine ezengeziwe ze-SiFive RISC-V, ukuze kwandiswe amandla ekhompuyutha omkhumbi-mkhathi wanamuhla izikhathi eziyi-100. Lokhu kwanda okukhulu ekusebenzeni kwekhompyutha kuzosiza ukuvula amathuba amasha ezinto ezihlukahlukene zemishini, njengama-autonomous rover, ukucubungula umbono, ukukhanya komkhathi, amasistimu okuqondisa, ukuxhumana, nezinye izinhlelo zokusebenza.

"Njengomholi wase-US kuma-semiconductors e-RISC-V, siyaziqhenya kakhulu ngokuthi siqokwe yisikhungo esihamba phambili somkhathi ukuze sinikeze amandla izinhlelo zokusebenza ezibaluleke kakhulu," kusho uJack Kang, iphini likamongameli omkhulu weSiFive kwezokuthuthukiswa kwamabhizinisi. “I-X280 ihlinzeka ngama-oda wezinzuzo ezinkulu zokusebenza ngaphezu kwamaphrosesa aqhudelanayo, futhi i-RISC-V SiFive IP yethu ivumela i-NASA ukuthi izuze ekwesekeni, ekuguquguqukeni, nasekusebenzeni kwesikhathi eside kwe-RISC-V yomhlaba wonke ye-ecosystem ekhulayo. Besilokhu sisho njalo ukuthi ngeSiFive, ikusasa alinamingcele futhi kuyasijabulisa ukubona ukuthi umthelela wokuqamba kwethu udlulela ngale kweplanethi yethu. »

Isinqumo seNASA kanye ne-Microchip ukukhetha idizayini ye-RISC-V Akuyona nje into entsha yesethi yemiyalo ye-RISC-V evulekile, engenanzuzo (ISA). Ngokusho kukaKang, ukwakheka kweRISC-V es enye yazo cishe izoba nesisekelo esikhulu sonjiniyela eminyakeni eyi-10, eyi-15 noma eyi-20 futhi, ngakho-ke, eUkubheja okuphephile kwe-NASA.

“Uma ubheka ama-chips e-PowerPC amanje, sekungamashumi eminyaka siwasebenzisa, bangaki abahleli bezinhlelo ze-PowerPC manje?” esho. Nakuba manje sesazi ukwakheka okuyisisekelo kwephrosesa ye-NASA ye-HPSC, kufanele silinde futhi sibone ukuthi umklamo uzokwenziwa kanjani ekugcineni, njengokuthi yikuphi ukuqina kwemisebe okuzosetshenziswa, kanye nanoma yikuphi okunye ukucubungula okuyisipesheli okudingwa ama-semiconductors amiselwe isikhala.

Njengoba zonke izinhlobo zemishini ye-NASA zidinga amakhono ekhompyutha, le chip ethuthukisiwe ingase izuze yonke imizamo yesikhathi esizayo ye-NASA, kungakhathaliseki ukuthi kuyimishini yesayensi phansi, ohambweni lwasemkhathini ojulile, noma izindiza eziqhutshwa abantu.

Ukwengeza, isimo esivulekile nesisebenzisanayo se-RISC-V sizokwenza umphakathi obanzi wabathuthukisi bezinhlelo zezemfundo nezesayensi ukuthi unikele futhi uthuthukise ama-algorithms esayensi nezinhlelo zokusebenza, kanye nokuthuthukisa imisebenzi eminingi yezibalo, izihlungi, imitapo yolwazi yenethiwekhi ye-neural eshintshiwe, nokunye.
